The present study aimed to evaluate the efficacy of the methanolic extract of Enteromorpha compressa against the 3rd larval stages and adults of Musca domestica and Calliphora vicina. Three concentrations of the methanolic extract of E. compressa (5, 10, and 20) g/L are used. The results showed that the mortality of M. domestica larvae varied from 26.6%, 66.6% to 100% at the concentration of 5 g/L, 10 g/L, and 20 g/L respectively after 24 h of treatment, but after 48 h at the same concentration, the mortality were 33.3%, 76.6%, and 100% respectively. The LC50 are 7.179 g/L for 24 h and 6.469 g/L for 48 h of treatment. The mortality of M. domestica adults were 33.3%, 46.6%, and 73.3% at the concentrations of 5 g/L, 10 g/L, and 20 g/L respectively after 24 h, and at the same concentration of extract, there were mortality about 43.3%, 66.6%, and 100% after 48 h respectively. The LC50 were 9.653 g/L for 24 h and 6.230 g/L for 48 h. The mortality of C. vicina larvae were 10%, 46.6%, and 83.3% at 5 g/L, 10 g/L, and 20 g/L concentrations respectively after 24 h and 23.3%, 53.3% and 90% after 48 h. The LC50 for larvae was 10.909 g/L for 24 h and 8.678 g/L for 48 h. The mortality of C. vicina adults were 20%, 33.3%, and 56.6% at concentrations of 5 g/L, 10 g/L, and 20 g/L at 24 h, and 43.3%, 63.3%, and 86.6% at 48 h. The LC50 for adult C. vicina were 16.778 g/L for 24 h and 6.368 g/L for 48 h after treatment.

本研究旨在评估浒苔的甲醇提取物对家蝇和 Calliphora vicina 的第 3 幼虫和成虫的功效。使用三种浓度的压缩棉的甲醇提取物(5、10 和 20)g/L。结果表明,5 g/L、10 g/L和20 g/L处理24 h后家蝇幼虫的死亡率分别为26.6%、66.6%~100%,但48 h在相同浓度下,死亡率分别为33.3%、76.6%和100%。24 小时的 LC50 为 7.179 g/L,48 小时的 LC50 为 6.469 g/L。5 g/L、10 g/L和20 g/L浓度下家蝇成虫24 h后死亡率分别为33.3%、46.6%和73.3%,相同提取物浓度下,死亡率分别为 43.3%、66.6%、和 48 小时后分别为 100%。24 小时的 LC50 为 9.653 g/L,48 小时的 LC50 为 6.230 g/L。5 g/L、10 g/L和20 g/L浓度下C. vicina幼虫的死亡率在24 h后分别为10%、46.6%和83.3%,48 h后死亡率分别为23.3%、53.3%和90% . 幼虫 24 小时的 LC50 为 10.909 g/L,48 小时为 8.678 g/L。在浓度为 5 g/L、10 g/L 和 20 g/L 时,C. vicina 成虫的死亡率在 24 小时分别为 20%、33.3% 和 56.6%,在 24 小时时分别为 43.3%、63.3% 和 86.6%。 48 小时。C. vicina 成虫 24 小时的 LC50 为 16.778 g/L,处理后 48 小时为 6.368 g/L。24 小时为 909 克/升,48 小时为 8.678 克/升。在浓度为 5 g/L、10 g/L 和 20 g/L 时,C. vicina 成虫的死亡率在 24 小时分别为 20%、33.3% 和 56.6%,在 24 小时时分别为 43.3%、63.3% 和 86.6%。 48 小时。C. vicina 成虫 24 小时的 LC50 为 16.778 g/L,处理后 48 小时为 6.368 g/L。24 小时为 909 克/升,48 小时为 8.678 克/升。在浓度为 5 g/L、10 g/L 和 20 g/L 时,C. vicina 成虫的死亡率在 24 小时分别为 20%、33.3% 和 56.6%,在 24 小时时分别为 43.3%、63.3% 和 86.6%。 48 小时。C. vicina 成虫 24 小时的 LC50 为 16.778 g/L,处理后 48 小时为 6.368 g/L。
